A patient diagnosed with cor pulmonale would most benefit from _because_______

an ACE-inhibitor medication: it will act as an inotrope and help to eliminate murmurs.

a diuretic: it will decrease preload and therefore decrease the workload of the heart.

a lab check of his troponin level: a troponin level will distinguish between right and left ventricular failure

a diuretic: it will counteract the dehydration present in most cases of cor pulmonale.

Answer and Explanation

The Correct Answer is B

A. While ACE inhibitors can be beneficial for heart failure management, they do not specifically eliminate murmurs and are not primarily used as inotropes in cor pulmonale management.
B. Cor pulmonale, characterized by right heart failure due to lung disease, often leads to fluid overload. A diuretic helps to decrease preload by promoting diuresis, thus reducing the workload on the heart and alleviating symptoms of congestion.
C. Troponin levels are used to assess myocardial injury rather than to distinguish between right and left ventricular failure; this is not a primary concern in cor pulmonale management.
D. Cor pulmonale is typically associated with volume overload rather than dehydration; therefore, using a diuretic to counteract dehydration is incorrect. The focus should be on reducing excess fluid to manage heart failure symptoms.

Correct Answer is D

Explanation

A. Serum creatinine levels within the normal range (0.6-1.2) do not specifically indicate intra-renal AKI.

B. A high 24-hour creatinine clearance is not typically associated with intra-renal AKI, as kidney injury often leads to decreased filtration and clearance.

C. A low serum creatinine level (0.5) would generally indicate good kidney function rather than AKI.

D. Casts in the urine are indicative of damage within the kidney tubules, which is a characteristic finding of intra-renal AKI, often due to cellular injury or necrosis within the kidney itself.

A. nosocomial pneumonia; lung tissue atelectasis B. lung tissue atelectasis; community-acquired pneumonia C. pulmonary edema; right heart failure D. pulmonary edema; left heart failure

Correct Answer is A

Explanation

A. Nosocomial (hospital-acquired) pneumonia is common in post-surgical patients, particularly those with atelectasis, as diminished ventilation can lead to infection. The green sputum and fever are signs of infection.

B. Lung tissue atelectasis may predispose a patient to pneumonia, but community-acquired pneumonia is less likely in a hospitalized patient, and the green sputum is more indicative of nosocomial infection.

C. Pulmonary edema is associated with fluid in the lungs but does not typically cause green sputum or elevated temperature, which suggest infection.

D. Left heart failure may lead to pulmonary edema but is not associated with green sputum or fever.
